2 Hookup
2.2 Back Panel Connections
Word Clock In and Out. These BNC connections allow Quantum 2626 to
receive and transmit word clock to and from other digital audio devices.
Power User Tip: In UC Surface, when using the BNC Clock input, you will need to set "BNC"
as the Clock Source and set the sample rate to correspond to that of the external device.
See Section 4.1 for details. A 75Ω BNC word clock cable is required to achieve proper sync.
S/PDIF In and Out. The S/PDIF connections allow two channels of audio to be
transmitted and received at rates up to 24-bit, 96 kHz. The S/PDIF I/O also allows all
Quantum 2626 interfaces to send and receive word clock to external digital devices.
Power User Tip: In UC Surface, you will need to set "S/PDIF" as the Clock Source and the
sample rate to correspond to the external device when using an external S/PDIF device as
your master clock. See Section 4.1 for details.
ADAT – S/MUX In and Out. These are the ADAT – Dual S/MUX connections
for your external digital devices. When recording or playing back at 44.1
or 48 kHz, each ADAT I/O will provide 8 of the 16 available channels
consecutively, from left to right. When recording or playing back at 88.2 or
96 kHz, each connection will provide four of the available eight channels.
These inputs and outputs do not function at 176.4 or 192 kHz:
ADAT 1 Input
44.1 / 48 kHz Channels 11-18 / 7-14
88.2 / 96 kHz Channels 11-14 / 7-10
When connecting a DigiMax DP88 to your Quantum interface, the ADAT
connections will also send and receive preamp control information for the DigiMax
DP88, so that it can be controlled directly from UC Surface or Studio One.
Power User Tip: In UC Surface, you will need to set "ADAT 1" as the Clock Source and the
sample rate to correspond to the external device when using an external ADAT device as
your master clock. See Section 4.1 for details. The ADAT 2 input cannot be used to receive
word clock.
Thunderbolt port. Use this port to connect your Quantum 2626 interface to
your computer.
Note: If your computer has Thunderbolt 2 ports, you'll need a bi-directional Thunderbolt
3 to Thunderbolt 2 adapter.
MIDI I/O. These are the MIDI input and output connections. MIDI stands for
"Musical Instrument Digital Interface. " However, MIDI can be used for many things
other than instruments and sequencing. The MIDI inputs and outputs allow
connection to a variety of MIDI-equipped hardware, such as keyboard controllers,
and can be used to send and receive MIDI Machine Control and MIDI Time Code.
Note: MIDI does not carry audio signals but is frequently used to trigger or control an
audio source, such as a virtual instrument or hardware synthesizer. You should ensure
that MIDI data is correctly sent and received by the appropriate hardware or software.
You may also need to route hardware sound sources' audio to the inputs of your
Quantum 2626 interface. Please consult the User's Manual of your MIDI devices for
help with MIDI setup and usage.
Power Button. This turns your Quantum 2626 on and off.
Power Connection. This is where you connect the Quantum 2626 interface's
external power supply. Your Quantum interface is equipped with a twist-lock power
connection, keep this in mind when connecting disconnecting it from your interface.
